Slant-D ring binder offers superior, professional presentation for a volume of paperwork. It holds 25 percent more paper than the same-size, round-ring binders. 5" ring capacity holds approximately 975 sheets. For durability and resilience, the cover material and overlays on front, spine and back are made of polypropylene. PVC-free, nonstick poly material resists ink and toner transfer for a clean impression overtime. Superior no-gap rings close securely and resist separation. Steel ringlets are attached to the inside back cover instead of the spine so pages lie flat. Straight-post design makes it easy to load content. Binder also features exposed rivets, a sturdy chipboard core and two clear interior pockets. Each pocket holds 40 sheets.Slant-D ring binder offers superior, professional presentation for a volume of paperwork.
